t Application led ANovember To all whom 'it may concern:

Be it known'that I,` EDwAnD LWmLIAMs, a citizen of the- United States,residing at Santa Cruz, in the county of'Santa (Jruz and State-ofCalifornia, have inventednew and useful Improvements 1n BuildingConstructionsgo'f which-the following is a speci- 'lhisinvention'relates to improvements in building constructions, andparticularly to the construction of floors. l

One of the objects of this invention is to produce a floor constructedof concrete or terra-cotta tile blocks, without the use of false lworkor temporary structures, such as are ordinarily emplo 'ed and which haveheretofore been consi ered indispensable in laying a' floor/of thistype.

Another Objectis to provide blocks of-new and improved shape which canbe laid upon and are supported directly bythe flanges of the cross-beamsof the building. The blocks are constructed to provide in conjunctionwith the beams-a mold into which the con- .1 crete may be pouredlwithout; .the use ofa false bottom. -When the concrete sets, the.

blocks are immovably fixed tothe beams thereby producing a strong andrigid-fl00r construction.

A further object is to strengthen the construction and firmly bind the'blocks and beams together by means of metal straps' which are passedover the beams and through thoblocks, and are fixedly embedded betweenthe blocks in the concrete fillin rc Still another object is theprovision of a floor construction which will afford bond-- infr placesfor the plaster which may be applied to the ceiling formed by the bottomof the floor, whereby the `plaster'will be securely anchored to theceiling.

In order that my invention ma be fully understood, I have describedinthe following specification a preferred embodiment thereof, and haveillustrated. the same in the accompanying drawings, in which, y; y

Figure lfis a plan view of the floor beams, blocks and metal stripsbefore the concrete filling has been applied. Fig. 2 is a verticalsection transversel of the lbeamseof acompleted floor; Fig. isasectionalfviewtaken on the line 3 3 lof Fig. 2; and Fig. `this a.perspective of one -ofmyimproved`floor bloc ts." i

Referring to the drawings, 5 designates Patented Dec. 10, 1912. 2, 191e.serial No. 590,267.

the floor beams which are preferably of T- bar formation, arranged withthe flanges at Athelower side of the beams with the web projectingupwardly therefrom. The beams are' spaced a suitable distance apart soas to accommodate a block (3, such as is illustratedin Fig. 4 betweenthem. 'lhc blocks are arranged in a series between the beams with the*shoulders 7 at either end of the blocks restin upon the flanges of thebeams. Each endo the block below the beams is beveledorv inclinedinwardly so that. the lower ed e will project. slightly beneath the,flanges-o the beams.

i Each block is provided with a plurality oflongitudinally extendingchannels or openings which render tre blocks lighter than they would beif constructed solid, and also provide passageways for the insertion offlexible metal straps l0. rlhe upper edges of the blocks are preferablyeut away to provide the channels 11, into which the concrete 12 flows,and securely anchors the blocksagainst lateral movement.

After the blocks have been laid in position between the beams, a metalstrap l0 is passed through each of the longitudinal openings 9 and islooped at l2 over the beams, as shown in Figs. 1 and 2. The stra s 10may be simply round metal rods or t ey may be flat straps of hoop ironor heavier stock if preferred. The lower endsl of the loops 12 areformed to engage with theupper part of the beam webs to maintain thestraps in the top of the passageways through the blocks until theconcrete is poured and set.

After the` blocks and metal straps have been arranged in position, thetop of the structure 'is covered with a layer of concrete which fiowsdown between the ends of the blocks and the beams upon which they restand a short distance into the channels in the blocks. The flan es of thebeams in conjunction with the b ocks prevent the concrete from flowingthrou h the structure at4 the bottom thereof, tiereby eliminatingthenecessit of false work or temporary structures w ile the floor is beingconstructed. The concrete also flows into any spaces which may be leftlbetween Vthe sides of adjacent blocks.

As will be evident from Fig. 2, the ends `o f theblocks do not sitclosely against the webs of the beams, the space between the ends of theblocks and the beam being filled with" concrete, as4 above-iv described.Since the concrete doesnot flow aroundand below the beams, itwill'be-evident that'a .space will be left beneath eaclbbeain-ibef tweenthe ends of adjacent; blocksL'This space or Adepression hasiipwardlyinclined-Y' walls which are formed b vthe beveled p'ortions 8 of theblocks. en plaster is'pplied to the bottom of this floor construction toform the ceiling of the room-underneath, these de ressionssarelflled-:by the plaster 13, wliic affords bondsv 14'zadapted.. tohold the plaster in place` If-it is not desired to plaster the lowersidel of a=`- floor construction, such as above` described, the

blocks may be extended attheir lower edges te abut against each otherand form a smooth and continuous'su'rface; Ifsuch form of blocks isemployed, it'would bel necessarily ositioned betweenthe beams 'frombeneati, one end of the block being first inserted over the'- flange ofa beam-an then the other end being raised into posi-YV tion and theblock being adjusted between` the beams so as toV be supported at eitheend u on the'flanges.-

blocls bein tween the ge upon the flanges being inserte crete beingbindingthe earns, blocks and strengthening straps into an inte ralvconstruction,

which is stron and dura le.

A floor construction including a 4series of floor beams,-bloclrsbetween the beams each block having an o en-ended channel disposedtransversely of t ebeam, the channels of successive blocks beinglinalinement, and a continuous flexible strap extending through thechannelsv of successive blocks and over successive beams, substantiallyas 2.
